GLP-1 Strength · Guide
Keeping your muscle on a GLP-1 — the complete guide
The medication is doing its job — the scale is moving. But the scale can't tell fat from muscle, and without strength training, 25–39% of the weight you lose can be muscle, not fat. This guide is what your prescriber means when they say "make sure you do resistance training" (strength training): what's happening, why it matters, and exactly how to train around the way the medication actually feels.
Why weight loss costs muscle
Any significant calorie deficit — surgical, dietary, or medication-driven — pulls from both fat and muscle. GLP-1 medications produce fast, sustained deficits, which is the point; but speed raises the stakes. That muscle is not just biceps: it's what sets your resting metabolism, stabilizes your joints, keeps your blood sugar handling sharp, and determines how strong you feel carrying groceries at 70.
Lose it, and two things happen: the weight comes back easier later (less muscle means a slower metabolism), and you arrive at your goal weight weaker than you started. Neither is inevitable. The research-backed counterweight is unglamorous: strength training that gets gradually heavier, plus enough protein. That's the entire idea of this program.
The two levers
1. Show up.Two to four short strength workouts a week — full-body exercises, 30–50 minutes. The signal that tells your body to keep muscle is simply working against resistance, and it doesn't take marathon workouts to send it. It takes showing up often and adding a little over time.
2. Eat protein. 1.6–2.2 grams per kilogram of bodyweight per day (about 0.7–1.0 g per pound), spread across the day. Appetite suppression makes this the harder lever for most people — which is exactly why we track it at every check-in. (The protein guide covers how to hit it when food has lost its appeal.)
Training on the days the medication wins
Every GLP-1 user knows the pattern: some days — often the day or two after injection day — energy craters and food is a chore. Generic programs break here. Ours bends:
Low-energy adjustment. Rate your energy at check-in. A 4 out of 10 or lower and your next workout adjusts — same exercises, same effort, about 40% fewer sets. You keep the streak; the plan absorbs the week. Showing up and doing less beats skipping, every time.
Rapid-loss guardrail. If your weight is dropping faster than about 1% a week on a two-week average, the risk to your muscle climbs — so the program stops adding weight to your lifts until the rate slows, and pushes the protein target harder.
Nausea-aware design. Floor core exercises swap to standing versions on rough days; warm-ups run longer; you stand up from the floor slowly. Small details, learned from the population, built in everywhere.
What a week looks like
Foundation (weeks 1–4): two full-body workouts — goblet squats, presses, rows, hip hinges, carries — at a comfortable effort that leaves 2–3 reps in the tank. Build (weeks 5–12): three workouts in a simple rotation, adding a little weight most weeks. Strength (weeks 13–24): three to four workouts, with progress checks that set your weights for the next phase. Every fourth week is a lighter catch-up week. You can read the full structure on the program page.
The rules we hold to
No medication brand names, ever. No dosing talk, no clinical claims, no before/after theater. Your prescriber owns every medication question — our lane is the training and the protein, and we stay in it. And one gate before anything else: tell your prescriber you're starting strength training. If they have any objection, that conversation comes first.
